제3도는 본 발명의 방법에 적용되는 진로(Path)의 각점 설명예시도.3 is an exemplary view illustrating each point of a path applied to the method of the present invention.

제4도는 본 발명의 고딕체 한글자소의 특정추출방법 흐름도.Figure 4 is a flow chart of the specific extraction method of the Gothic Hangul alphabet of the present invention.

Claims (5)

한글자소 진로(Path)의 총 세그먼트를 검출하고, 그 임의의 세그먼트 및 다음 세그먼트의 폭 검출한 후 그 양폭의 차이 절대값을 임게값과 비교하여 상기 진로의 폭변화를 검출하고, 상기 폭변화가 검출될 때 상기 임의의 세그먼트 및 다음 세그먼트의 중심점과, 상기 진로의 좌우폭 및 상하폭을 검출하여 그 값들 및 상기 임게값으로 부터 5종류의 진로모양을 추출하고, 상기 마지막 세그먼트에서 폭변화가 검출되지 않으면, 이전의 세그먼트에서 폭 변화가 발생되어 있는 경우에는 시작, 중간, 끝 세그먼트의 중심점을 검출한 후 그 값들 및 상기 임계값으로부터 3종류의 진로모양을 추출하고, 이전의 세그먼트에서 한번도 폭변화가 발생되지 않는 경우에는 현재 진로의 중심점 및 이전진로의 중심점을 검출하여 그 값들로부터 3종류의 진로모양을 추출하게 함으로 특징으로 하는 자획의 폭변화에 의한 고딕체 한글자소의 특징 추출방법.Detects the total segment of the Hangul alphabet path, detects the width of the arbitrary segment and the next segment, detects the width change of the path by comparing the absolute value of the difference between the two widths with the threshold value, and the width change is When detected, the center point of the arbitrary segment and the next segment, the left and right widths and the upper and lower widths of the path are detected and 5 types of path shapes are extracted from the values and the threshold value, and the width change is not detected in the last segment. Otherwise, if a width change occurs in the previous segment, three center paths are extracted from the values and the thresholds after detecting the center point of the start, middle, and end segments. If it does not occur, it detects the center point of the current course and the center point of the previous course and extracts three kinds of career shapes from the values. Gothic Hangul basil method of feature extraction by the width change of the character stroke, characterized. 제1항에 있어서, 상기 진로의 좌우폭이 상하폭보다 크면, 상기 좌우폭이 상기 임계값보다 큰가의 여부에 따라 그 진로를 모양 코드″11″, ″1″로 추출함을 특징으로 하는 자획의 폭변화에 의한 고딕체 한글자소의 특징 추출방법.2. The width of the stroke according to claim 1, wherein if the left and right widths of the path are larger than the upper and lower widths, the paths are extracted as shape codes ″ 11 ″ and ″ 1 ″ according to whether the left and right widths are larger than the threshold value. A method of extracting features of Gothic Hangul alphabets by change. 제1항에 있어서, 상기 진로의 좌우폭이 상하폭보다 작으면, 상기 임의의 세그먼트 및 다음 세그먼트의 중심점 차이 절대값이 상기 임계값보다 작을 때 그 진로를 모양 코드 ″22″로 추출하고, 그 차이 절대값이 임계값보다 클 때 상기 임의의 세그먼트 중심점이 다음 세그먼트의 중심점 보다 큰가의 여부에 따라 그 진로를 모양 코드 ″23″, ″21″로 각기 추출함을 특징으로 하는 자획의 폭변화에 의한 고딕체 한글자소의 특징 추출방법.2. The method according to claim 1, wherein if the right and left widths of the course are smaller than the top and bottom widths, the course is extracted as a shape code ″ 22 ″ when the absolute value of the center point difference between the arbitrary segments and the next segment is smaller than the threshold value, and the difference is determined. When the absolute value is larger than the threshold value, the path is extracted with shape codes ″ 23 ″ and ″ 21 ″, respectively, depending on whether the arbitrary segment center point is larger than the center point of the next segment. Feature Extraction Method of Gothic Hangul Alphabet. 제1항에 있어서, 상기 시작 세그먼트의 중심점 및 끝 세그먼트의 중심점 차이 절대값이 상기 임계값보다 크면 그 진로를 모양 코드 ″4″로 추출하고, 그 차이절대값이 임계값보다 작으면 상기 시작 세그먼트의 중심점 및 중간 세그먼트의 중심점 차이 절대값이 상기 임계값보다 큰가의 여부에따라 그 진로를 모양코드 ″5″, ″2″로 각기 추출함을 특징으로 하느 자획의 폭변화에 의한 고딕체 한글소자의 특징 추출방법.The method of claim 1, wherein if the absolute value of the center point difference between the center point and the end segment of the start segment is greater than the threshold value, the course is extracted as a shape code ″ 4 ″; and if the absolute difference value is less than the threshold value, the start segment is obtained. According to whether the absolute value of the difference between the center point and the middle segment of the middle segment is greater than the threshold value, the paths are extracted with shape codes ″ 5 ″ and ″ 2 ″, respectively. Feature extraction method. 제1항에 있어서, 상기 현재 진로의 중심점 및 이전 진로의 중심점 차이 절대값이 상기 입계값보다 작으면 그 진로를 모양코드″32″로 추출하고, 그 차이절대값이 임계값보다 크면 상기 현재진로의 중심점이 이전진로의 중심점보다 큰가의 여부에 따라 그 진로를 모양코드 ″33″, ″31″로 각기 추출함을 틀징으로 하는 자획의 폭변화에 의한 고딕체 한글자소의 특징 추출방법.The method of claim 1, wherein if the absolute value of the difference between the center point of the current course and the previous course is less than the threshold value, the course is extracted as a shape code ″ 32 ″, and if the difference is greater than a threshold value, the current course is taken. A method of extracting features of Gothic Hangul alphabets by varying the width of the strokes by extracting the paths with shape codes ″ 33 ″ and ″ 31 ″, respectively, depending on whether the center point is larger than the center point of the previous path. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
